革胡子鲶属热水性鱼类,当水温降至7℃时,就有死亡的危险。为此,我们做了利用温泉水作革胡子鲶越冬的试验。一、材料的选择和方法湘潭县碧泉潭温泉,常年水温在19℃以上,水清如明镜,水流量为0.73T/分钟,无污染,水质条件利于鱼类越冬。 1、越冬池越冬池选择在温泉水出口10米远的一侧,避风向阳,土质坚固,不漏水,池边水泥护坡,长方形,面积0.25亩,水深0.8至1米,按长边对角线设置进出水口。在进出水口处安置钢丝拦鱼栅。 2、越冬池在越冬期间(12月至2月)用纤维塑料布搭棚复盖。塑料布距水面1米,先用细竹木扎成三角架固定,然后在其上盖一层塑料
Catfish is a hot water fish, when the water temperature dropped to 7 ℃, there is a danger of death. To this end, we made the use of hot spring water for catfish wintering catfish experiment. First, the choice of materials and methodsBaichuitan hot springs in Xiangtan County, perennial water temperature above 19 ℃, water clear as the mirror, water flow 0.73T / min, non-polluting, water conditions conducive to winter fish. 1, wintering ponds wintering ponds Choose the hot spring water outlet 10 meters far side, sheltered the sun, strong soil, watertight, poolside slope protection, rectangular, an area of 0.25 acres, water depth 0.8 to 1 meters, according to the long side of the diagonal Set the inlet and outlet. In the inlet and outlet to place steel barricades. 2, wintering pool during winter (December to February) covered with fiber plastic cloth scaffolding. Plastic cloth 1 meter from the water, first with fine bamboo tie into a tripod fixed, and then covered with a layer of plastic
